Quick Answer

Formula: gal/h = L/s × 951

Multiply any L/s value by 951 to get gal/h.

Reverse: L/s = gal/h × 0.001052

Mental Math Tricks

Exact factor

1 L/s = 951 gal/h.

Unit chain

m³/s × 1000 = L/s × 60 = L/min. Use this chain for quick conversions.

Reverse

Multiply result by 0.001052 to recover the original L/s value.

Frequently Asked Questions

About L/s and gal/h

L/s (L/s)

Liters per second (L/s) is widely used in water supply engineering, fire protection, and irrigation where liter-scale flows are practical. One L/s = 0.001 m³/s = 60 L/min.

Fire hoses typically deliver 7–25 L/s. Municipal water distribution systems are designed for flows in L/s. Swimming pool filtration systems run at 1–10 L/s. A garden hose delivers about 0.3 L/s.

Interesting fact: The human heart pumps about 0.083 L/s (5 L/min) at rest, rising to 0.333–0.5 L/s (20–30 L/min) during intense exercise. Over a lifetime, the heart pumps approximately 200 million liters of blood.

gal/h (gal/h)

Gallons per hour (gal/h) is used for slower flow rates such as fuel consumption, slow drip irrigation, and residential water softeners. One gal/h = 1.0514 × 10⁻⁶ m³/s ≈ 0.0631 L/min.

Vehicle fuel consumption at highway speeds is typically 2–8 gal/h for gasoline engines. Water softeners regenerate at 0.5–2 gal/h. Fuel oil burners for home heating consume 0.7–3 gal/h depending on output.

Interesting fact: A dripping faucet (one drip per second) wastes about 3,000 gallons per year — roughly 0.34 gal/h. A running toilet can waste 200 gal/h, adding up to nearly 2 million gallons over a year if unrepaired.

About L/s to gal/h Conversion

Converting L/s to gal/h is essential across hydraulic engineering, HVAC, water treatment, fire protection, and medicine. SI units (m³/s, L/s) are standard in science; European engineering uses m³/h; US systems use GPM and CFM; medical applications use L/min.

Quick reference: 10 L/s = 9510 gal/h. Reverse: 1 gal/h = 0.001052 L/s. Factor: 1 L/s = 951 gal/h.

All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
